Gentlepersons:
I have been throwing a mid-range porcelain and saving scraps in a 5 =

throwing bucket with slip for a few days and when I went back there was =
quite a stench, rotten. It is the first time I experience this. What =
is going on? Any suggestions on how to avoid?
The stench was so bad that I am proposing a new PPA rule. "Thou shall =

"uncivilized".

Stinky recycle clay has occurred to me many times. I've never had a problem
with the clay itself due to this stinkiness and am not totally sure what is
causing it, but it smells like mold to me, which has never effected the final
outcome of the work.

Mold it is - it rattled me the first time I encountered it. I thought I had done something wrong. There is no reason not to use it, unless, of course, you mind the smell terribly.

For those of you who dislike the stink, try some Listerine in the mix. I =
sometimes use that in my throwing water to avoid the stinks there and =
thus it goes into the recycle already.

Just been getting some smelly recycle clay.
But the reason was simple.
The plumbing to my undersink catch bin was such that some back flow from the
upstairs loo was able to get into it!!
Mixed with other clays it is OK and the smell has gone, or I've got used to
it.

Nature is pretty smart about stuff like this...a bad smell is usually
a warning! No expert here, but I'd take a guess that your problem is mold.
And no, it's not harmless. I recently had to go through a series of over 300
needle sticks (in two sessions) to find out what was making me so ill. MOLD,
MOLD, MOLD! I don't know if mold is just getting more press time lately but
it seems to be effecting more and more people adversely.
I had three choices: weekly allergy shots for 5 years (if you miss a
week, back to square one); take medication that either put me to sleep or
put me on the roof; get rid of the mold.
Luckily, it's not hard to get rid of the mold, as long as it's not
under the floors or in the walls, or some other hidden spot. For me, it was
just a matter of adding a capful of chlorine bleach to my buckets of
slip/clay scraps and my throwing water. Since I have an open-air studio (a
nice way of saying that I throw in a broken-down shack that no longer has
windows), 10 feet away from a cypress bayhead (for you Northerners, that's a
swamp), I try to keep fans on to get the air moving and make some attempt to
dry things out.
My most favorite clay, P10 by Highwater, comes to me peppered with
black mold in the bag. I open only one bag at a time, covering the clay with
a cloth that I spray with a strong bleach solution. Seems to work for me and
I haven't noticed any difference in throwing, glazing, or firing.
Have a great day, everyone,

Try this. Take a coil of of the "rotten" porcelain and a coil of the
porcelain you usually use and bend them in half. You may find that the
"rotten" porcelain doesn't show signs of cracking. If so this may mean you
have a porcelain with smaller particles which is more elastic.

But surely once the process has run long enough to
modify the clay, it would be OK to 'clean it up'.
That wouldn't change the plasticity, just the smell
and maybe the allergens, right?
